Parathyroid adenoma is the most common cause of primary hyperparathyroidism. It is more common in females by the ratio of 4:1. Histologically parathyroid adenoma composed of different cell types, Chief cells and Oxyphilic cells. Chief cell parathyroid adenoma is the most common type. To study the Cytohistological variants of parathyroid adenoma in our tertiary care hospital. We are presenting three cases of Parathyroid adenoma (Chief cell, Oxyphilic and mixed types), who presented with nephrocalcinosis and swelling in front of neck. Parathyroid adenoma, Chief cell parathyroid adenoma, Oxyphilic parathyroid adenoma and mixed type of parathyroid adenoma. Parathyroid adenoma is the most common cause for primary hyperparathyroidism. 1 Histologically parathyroid is composed of different cell types - Chief cells and Oxyphilic type. Chief cells are further categorized as conventional chief cells and water clear cells. Chief cell parathyroid adenoma is the most common type. Normal parathyroid glands are too small to be detected on imaging (usually 5x3x1 mm), weighs 40 - 50mg, but in parathyroid disease typically results in enlargement of the glands allowing for visualization.
